1. A display panel, comprising:
a display function layer comprising a plurality of light-emitting elements and a pixel definition structure surrounding the plurality of light-emitting elements;
an anti-reflective function layer disposed on a light emitting side of the display function layer and comprising a first refractive index pattern; wherein the first refractive index pattern overlaps with the pixel definition structure;
a base material layer disposed between the anti-reflective function layer and the display function layer and comprising a light uniformizing structure; wherein the light uniformizing structure comprises a first inclined sidewall, and in a light emitting direction of the plurality of light-emitting elements, the first inclined sidewall is inclined towards a direction away from a light-emitting element adjacent to the first inclined sidewall.
